SAW-SET.

SPECIFICATION forming part of Letters Patent N 0. 591,478, dated October12, 1897.

Application filed January 7.1397. Serial No. 618.357. (No model.)

To aZZ whom .it may concern:

Be it known that I, JAMES A. KIDWELL, a citizen of the United'States,residing at Gorton Heights, in the county of Centre and State ofPennsylvania, have invented certain new and useful Improvements inSaw-Sets; and I do hereby declare the following -to be a full, clear,and exact description of the invention,

such as will'enable others skilled in the art to which it a'ppert-ainsto make and use the same.

This invention has reference to a novel construction in a saw-set; andit has for its object to provide a novel, inexpensive, and du rabledevice of this character.

The invention consists win the features of construction hereinafterfully described and with an overhanging guide 2 and at its other endwith the uprising overhanging arms 3, and upon which the die 4 issupported. The said die 4 is provided at its lower end with the guide 5,that is situated within an upright opening 6 in the body portion 1. Thesaid die is connected at its upper end with an operating-handle 7,thatis mounted upon the arms 3 and which serves to raise and depress thesaid die. The particular construction for operating the die consists ofthe handle 7, pivoted upon the arms. 3, andto which the upper end of thedie 4is eccentrically pivoted. In this way it is seen that as the handle7 is turned upon its pivot the die is raised and depressed. The bodyportion 1 is cut away just below the die 4 to provide the socketS,

into which the-said die fits- Situated within an opening just in therear of the socket 8 is a gage-block 9, that is pivoted upon a nut 10,

carried by a screw-threaded bolt 11, that is situated within a' recessin the said body portion 1. block 12, that is secured by a screw 13,while the said bolt 11 is also provided with a milled wheel 14, by meansof which it can be turned to advance or retract the gage-block 9. The

The rear end of said bolt is held in a vertical movement of the die iscontrolled by a pivoted finger 15. This finger 15 is pivoted between thearms 3 and has an extension 16 at its other end that is situated Withina rece ss 17 in the rear side of the die. An adj usting-screw 18 passesthrough the body portion 1 and engages the lower face of the finger 15to control the downward limit of the same and consequently the downwardmovement of the die toregulate the set of the saw-teeth. The guide 2 isprovided with a plurality of screw-threaded openings 19,- that receivethe screw-threaded bolt 20, by means of which the saw is clamped inposition, and which, furthermore, allows saws of various widths to beheld in position.

It is seen from the foregoing description that theteeth of the saw canbe set quickly and efficiently, and that, furthermore, by means of theadjustable gage-block 9 and adj ustable die 4, together with theadjustable set-screw 20, that not only can saws varying in width beaccommodated but saws varying in width can be set at the desired angle.The device is simple and made of few parts, and, furthermore, thedevices for adjusting the same can be easily manipulated, while thewhole device is inexpensive, comparatively small, and effective.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A saw-set consisting of a body portion having an overhanging guidebetween which and said body portion the saw is to be inserted, a pivotedgage-block pivoted Within an opening in said body portion, a die mountedabove said gage-block, and devices for operating said die.-

2. A saw-set consisting. of a body portion having a guide, an opening insaid body por* tion, a rotatable screw-threaded bolt situated withinsaid opening and provided with devices for turning the same and with anut, a gage-block pivoted to said nut, and an adjustable die and devicesfor operating the same,

3. A saw-set consisting of a body portion having an adjustablegage-block andaguide, a die and devices for operating the same, a slotin said die, and a pivoted finger having an extension situated withinsaid slot, and a set-screw for controlling the extent of move- Intestimony whereof I have signed this ment of said pivoted finger.specification in the presence of two subscrib- 1o 4.InasaW-set,abodyportiomagage-block, ing witnesses. carried by said bodyportion, an upright 5 opening adjacent said gage-block, a die and JAMESkIDVELL' devices for operating the same, and a guide \Vitnesses: uponthe lower end of said die and situated GEO.

within said upright opening. JACOB BEIGHTOL.
